Shielding termination (1 Viewer)

[calvin_clements]

I just got a used set of Audio Tekne cables with spades. The shielding wire is attached to the negative spade on one end and not the other (with one pair)...while the shielding wire is not attached to any spade on the other wire. Should I attach the shielding to the negative spade on both ends, one end or no ends? I want to much sure system is as grounded as possible to alleviate hum in system.
Thanks,
Calvin

Hum isn’t introduced into a system through the speaker cables, since it is a high-level signal. Therefore shielding speaker wires is unnecessary.

That said, the generally accepted place to tie in a shield is at the signal negative. I’d do it at both ends, although it’ll function just fine connected at one end only. If you do one end only, the connected end should go to the amplifier.
